XFM-5050-UV Binning Structure
XFM-5050-UV LEDs are tested for radiometric flux and wavelength at a drive current of 2.0 A (equivalent to 500 mA/chip), 20 ms single pulse at 250 C and placed into one of the following radiometric flux (FF) and wavelength (WWW) bins. The LEDs can also be driven at other drive currents, to achieve the correlated flux values listed in the table.
Radiometric Flux Bins
Wavelength Bins
Note 1: Luminus maintains a +/- 6% tolerance on flux measurements and +/- 1 nm on wavelength measurements.
Note 2: Individual bins are not orderable. Please refer to product ordering information on page 3 for a list of ordering part numbers.

Note 1: Product lifetime is a function of drive current. Sustained operation at absolute maximum current of 3.2 A will result in a reduction of device lifetime compared to typical forward drive currents (1.4 A-2.0 A). Actual device lifetimes will also depend on junction temperature. Contact Luminus for information on product lifetime.
Note 2: Correlated minimum flux values are for reference only. XFM-5050s are tested and binned only at the test current of 2.0 A.

Note 1: Ratings are based on operation at a constant junction temperature of Tj = 25 ºC. Test conditions: 2.0 A, 20 ms pulse at 25ºC.
Note 2: XFM-5050-UV LEDs are designed for operation up to an absolute maximum forward drive current as specified above. Product lifetime data is specified at typical forward drive currents. Sustained operation at absolute maximum currents will result in a reduction of device lifetime compared to typical forward drive currents. Actual device lifetimes will also depend on junction temperature.
Note 3: Caution must be taken not to stare at the radiation emitted from UV LEDs.

XFM-5050-UV
Product Datasheet - Preliminary
1. UV Light
XFM-5050 LEDs are short wavelength, deep UV LEDs. During operation, the LED emits high intensity UVC radiation, which is harmful to skin and eyes. UV light is also hazardous to skin and may cause cancer. Avoid exposure to deep UV light when LED is operational.
2. Static Electricity (ESD)
While XFM-5050 LEDs have built-in Zener protection diodes, they are particularly sensitive to ESD (Electrostatic Discharge). Static electricity and surge voltages seriously damage UV LEDs and can result in complete failure of the device. Precautions must be taken against ESD when handling or operating these devices.
3. Operating Conditions In order to ensure the correct functioning of these LEDs, compliance to maximum allowed specifications is important. UV LEDs are par-ticularly sensitive to drive currents that exceed the max operating specifications and may be damaged by such drive curents. The use of current regulated drive circuits is strongly recommended when operating these devices. Customers should also provide adequate thermal management to ensure LEDs do not exceed maximum recommended temperatures. Operating LEDs at temperatures in ex-cess of specification will result in damage and possibly complete failure of the device.
Precautions for storage, handling and use of UV LEDs
